Help needed in finding a part please

Hey all, I am in great need of a part for my 1992 K1500 I am not exactly sure what its called but its the little "box" that you plug the radio wires, AC/heater wires and the antenna wire into. Mine is pretty well done for and i havent had any luck in finding one. I have looked around at the junkyards and can find them all day long but none of the pickups ac/heater controls have the recirculate button and mine does, therefore i need one with the recirculate button as well. I figured i would ask anyone here if they had a spare parts pickup or something and if you would sell me that "box" out of it.

Thanks in advance
Wesley
